A standard distribution regards 95% of all data being within 2-standard deviations of either side. Similarly, within one standard deviation either way is 68% of all data. This creates a bell curve distribution. An abnormal distribution would be erratic and not follow such a statistical structure of representation.

What are some examples of abnormal and normal distribution in statistics?
IQ is normally distributed in the general population. Age is not.
In statistics if a condition occurs to more than 10 percent of the population is this considered abnormal?
I am under the assumption that in statistics, if the ten percent condition is not met, meaning that the sample size is more than 10% of the population, then the result is not a normal distribution.
Is normal distribution also a probability distribution?
Yes. When we refer to the normal distribution, we are referring to a probability distribution. When we specify the equation of a continuous distribution, such as the normal distribution, we refer to the equation as a probability density function.
True or False A sampling distribution is a probability distribution for a statistic?
The statement is true that a sampling distribution is a probability distribution for a statistic.
Is A normal distribution is any distribution that is not unusual?
No, it is the name given to the Gaussian distribution.
